I think your Z-sustain may be bad. If you run the set for some time, then turn it off, see if the heatsinks on the Z-sustain feel noticeably cooler than the Y-sustain. I am confused though - I thought you had the vertical lines issue which was the Y-sus/buffers. And then the Z-sustain goes bad. It's very odd. Definitely not an easy first project!

This first project makes me wanna read books instead of melt my brain with TV

At first, it had that bluish screen that was all pix-elated. One afternoon, I turned the set on to get the readings you suggested, and I heard a "pop" and I lost the picture totally. That's when the Y-Sus board started "surging" and the readings were fluctuating every three seconds. So, I unplugged the Y-Buffer boards, and the Y-SUS board stabilized. So, I ordered the Y-Buffer boards, upper and lower, and my picture came back, but I still have that weird pix-elated picture. I understand why you're confused about this situation.

I'm going to turn it on while I do homework, that should give it enough time to warm up.

Well, as luck would have it, my television has been on since I checked the Z-bias earlier. Both the Y-Sus and the Z-Sus heat sinks are hot, but I don't think either one is hotter than the other.

Can you supply a clear picture of your Z-sustain board?

Here's a video as well. That clicking noise is my dog walking around, not the television popping!

I'm planning to order the Z-Sustain today. Keep your fingers crossed.

Goood afternoon!

It's been a few months since I updated this thread, school has had me busy this past semester.

I replaced the Z-Sustain board in this display, and the fault didn't go away. After school was out, I ordered a Y-Sustain board and installed it.

I'm happy to report the television has a perfect display. The fault is gone.

Is there any tuning I should do? I'm afraid to attempt anything without consulting with you first!

Have an amazing day!
